General Description
The AOZ1117 is a low dropout positive adjustable or
fixed-mode regulator with minimum of 1A output current
capability. The product is specifically designed to provide
well-regulated supply for low voltage IC applications such
as high-speed bus termination and low current 3.3V logic
supply. The AOZ1117 is also well suited for other appli-
cations such as VGA cards. The AOZ1117 is guaranteed
to have lower than 1.4V dropout at full load current mak-
ing it ideal to provide well-regulated outputs of 1.25V to
5.0V with 2.75V to 14V input supply.
